実験手順

2-Oxa-7-azaspiro[4.4]nonane HCl salt (0.07 g, 0.43 mmol) was dissolved in dichloromethane (2 ml). Triethylamine (0.064 ml, 0.47 mmol) was added, followed by 2-methyl-4-(1-(5-phenyl-1,3,4-oxadiazole-2-carbonyl)azetidin-3-yloxy)benzaldehyde (0.13 g, 0.36 mmol) and sodium triacetoxyhydroborate (0.152 g, 0.72 mmol). The resulting mixture was stirred at ambient temperature overnight. The reaction mixture was diluted with dichloromethane (10 ml) and then shaken with NaHCO3 (sat. 3 ml). The two phases were separated by the use of a phase separator. Evaporation of the organic phase afforded crude material, which was purified by preparative reverse-phase HPLC at pH 10 to give 85 mg (50%) of the desired product as a solid.
